This invention relates to machines and devices designed particularly forthe treeing of boots and shoes. I

A boot or shoe is made on a last to which 6 it is conformed, and onwhich it remains while the series of operations are performed on thearticle. After the various mechanical operations are completed it isgenerally necessary especially in highly skilled work, to subject theupper to a treeing operation where it is ironed and given a finishingtouch. The machine'used for this purpose is a treeing machine whichhas atree comprising an expansible leg composed of relatively movable legparts and a series of expansible toot parts. In order, however, toperform the treeing operation in such a machine, it is necessary to takethe last out of the shoe and place the latter over the foot and leg ofthe tree. This not only results in a last of the shape which has beencarefully preserved while the last was on the shoe, but requires that anumber of different foot pieces be kept on hand.

One of the objects of this invention, therefore, is to provide means inthe nature of an attachment for a treeing machine which is soconstructed and adapted as to not only receive the last while remainingon the shoe and hold it firmly in position on the treeing machine legfor the treeing operation, but which is adapted for the ordinary last asused in the manufacture of shoes. I

Another object is to provide a treeing machine. of the characterdescribed which is simple in construction, effective in its action andeconomic to manufacture.

Further objects will appear from the detail description taken inconnection with the'accompanying drawings, in which Fig. l is anillustration of the type of treeing machine embodying this invention;

tatably mounted a series of legs composed of relatively movable parts ormembers 3 and 4. Arranged Within the leg is an expanding device 5arranged to couple with a bell crank lever 6 connected by a rod 7 to atreadle 55 which is usually raised by a strong spring. The expandingdevice is also acted upon by a. spring 8. A strip 20 is mounted in themember 4 and to this is attached one of a series of i'ore parts (notshown) as usually 00 employed. in treeing machines of this type; i insuch a case the fore part forms a continuation of the formed heel part30 at the end of the member 3. The parts so far described may be of anysuitable or usual construction, the structure being such that the spring8 operates on the expander 5 to yieldingly per- .mit the members 3 and 4and the heel and foreparts thereon to collapse when this expander iscoupled with the bell crank lever 6, and the treadle depressed, theexpander is operated to expand the members 3 and 4 so as to spread apartthe heel part 30 and the usual iore part (not shown).

In accordance with this invention the end of the leg is formed toreceive a last of any suitable or usual construction, that shown being alast composed of a heel part 10 and a forepart 11 providing a recesstherebetween, the forepart having a face 12 within the recess while theheel part has a socket 13 arranged to receive the usual last pin. Inorder to couple the last 2 to the tree leg, the heel part 30 is providedwith a bar 15 pivoted on .this part and having formed therein a socket16 adapted to receive a last pin 17. In order to secure this last pin inposition the latter has a ball 18 retained within a recess therein .inwhich is also arranged a spring 19, the edges of the recess being peenedover to retain this ball in position. The last pin is thereby removablybut firmly secured within the heel part so as. to enter the last socket13 in order to provide a coupling for holding the last on the leg.Guided within the le part .4 is the strip 20 having at its end a we go21 provided with a gripping face 22 adapted to engage the face 12 on thelast forepart when the strip and wedge are within the recess between thelast parts. The strip may be the usual one now employed for attachingthe fore parts to the tree as heretofore described. In order, however,to adapt it for the purpose herein described, a rib 23 on the stripengages with a groove in the Wedge. A not-ch 2 1 is provided in thestrip 20 for receiving a bar carried by the wedge 21 and bridging thegroove thereof. A plurality of aligned apertures 26 are provided in theopposite flanges of the groove in wedge 21 for removably 1e cciving pin27. The pin 27 is dsposed to ride upon the upper surface of rib and maybe placed in any selected pair of aligned. apertures 26 in order to varythe inclination of the wedge that the device may be readadapted toreceive lasts of different sizes. lVith this construction the wedge canbe removable and adjustable but firmly secured on the st 'ip.

In order to place a last with a shoe thereon in operative relation withthe tree leg, the last is placed on the pin 17. The strip 20 is thenmoved into the recess between thelast p rts so that a gripping face 22of the wedge will engage the face 12 on the last forepart. T his is nonevvhile the expander is in retract- (i position and with the leg memberscontract-ed. Upon depression of the treadle the same will operate on theexpander to spread the members 8 and 4 apart; this will move the pin 17relative the strip or element 20 so as to secure the coupling betweenthe last and the tree leg and firmly hold the latter in position. Theshoe can now be ironed as usual. This ironing can even extend to the topof a high boot, it can extend over the leg parts 3 and 4; It will beseen that the provision of the wedge, which can be placed to any extentwithin the recess, there can be a lost motion before the faces 22 and 12engage; this lost motion can be used to expand the members 3 and 4: toconform to the top of a high boot. After the shoe has been ironed thelast can be taken off by contracting these members.

at will, therefore, be seen that the invention accomplishes its objects.A treeing machine is provided which is adapted to receive the last asordinarily used in the manufacture of boots and shoes. lit is,therefore, not necessary to take the shoe off the last but the treeingand ironing operations can be performed even on high top boots while thelatter remains on the last. The structure is such that it is readilyadapted to any type treeing machine with the minimum of alterations.Moreover, the treeing machine may still be used by removing thecouplings 17 and 21, (which are complete and self-contained andremovable as a whole from the leg members) and by attaching the usualfore-parts.

It will he understood that while the particular embodiment shown anddescribed, is to a knuckle hinge last, the invention is susceptible ofemployment to other types and forms of last. It will, furthermore, beunderstood that certain features and sub-combinations are of utility andmay be employed without reference to other features and subcombinations.That is contemplated by and is within the scope of the appended. claims.It is, therefore obvious that various changes may be made in details ofconstruction within the scope of the appended claims, without departingfrom the spirit of this invention. It is, therefore, to be understoodthat this invention is not to be limited to the specific details shownand described.
